JOSEPH R. ROYER, OF LANCASTER, PENNSYLVANIA, ASSIGNOR S. ROYER, OF SAMEPLACE.

To MILTON DOOR-SECURE R.

SPECIFICATION forming part of Letters Patent No. 485,661, dated November8, 1892. I

Application filed July 29, 1892. Serial No. 441,549- (No model.)

To aZZ whom it may concern):

Be it known that I, JOSEPH R. ROYER, a citizen of the United States,residing in Lancaster, in the county of Lancaster and State ofPennsylvania, have invented certain Improvements in PortableDoor-Fasteners, of which the following is a specification.

This invention relates to improvements in that class of door-fastenerswhich can be carried about in the pocket and removably secured todoor-frames to lock the doors in a closed position, and is moreparticularly intended for use by traveling salesmen and other personstemporarily occupying rooms the doors of which are unsupplied withbolts; and the object of the invention is to produce a simple, cheap,and efficient portable doorfastener which can easily be carried in thepocket or stored away in the corner of ahandba 'Ihe invention consistsin the construction and combination of the various parts, as hereinafterdescribed, and then specifically pointed out in the claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a view of the fastener secured to a jamb having portions cutaway and showing the door closed and the locking-levers of the fastenerfolded in to permit the door to be opened. Fig. 2 is a similar viewhaving portions cutaway and showing the locking-levers turned outward ina horizontal position to lock the door. Fig. 3 is a horizontal sectionon the line :1: m, Fig. 1, the view being taken from the direction ofthe arrow c. Fig. 4 is a top or plan view of the fastener, and Fig. 5 aninner face view of the side of the box to which the strut is pivotedthat supports the upper locking-lever in a horizontal position. Fig. 6is a side view of one of the fasteners having only one looking-lever,the fastener being detached from the door-jamb; and Fig. 7, a similarView, partly in section, the locking-lever being shown in the positionit occupies when opened out by broken lines y.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A represents a door, and B thejamb against which the door is closed.

C is a small elongated box having one side open. This box is secured tothe face of the jamb with its open side turned toward and flush with theedge thereof by thumb-screws a, which pass through correspondingopenings in opposite sides of the box and are screwed into the jamb. I

Near each end of the open side of the box there is a locking-lever Dhinged. When 6c opened out in a horizontal position, as shown in Fig. 2,the locking-levers engage the side of the door and prevent it frombeingopened, and when they are closed they fold toward each other andclose the open side of the box, the meeting edges being-beveled onopposite sides, so that the upper locking-lever laps the lower andprevents it'from being accidentally jarred into an open position. In theinner edge of each locking-lever there is formed a notch d, by which itcan be opened the more easily, and on the outer side of the hinged edgethere is formed a shoulder b, which limits the outward movement of saidlevers by contact with the end of the box. In a recess e in the innerface of the plate E of the box C and adjacent to the edge adjoining thelock ing-levers there is pivoted a strut F. When the locking-levers areclosed down to cover the open face of the box, strut F occupies avertical position in recess a; but when the said levers are turned outhorizontally the upper end of thestrut is pulled outward, passingthrough a curved recess f in the edge of the upper locking-lever untilits movementis arrested by the shoulder g, forming the outer end of saidrecess. This strut serves to prevent the accidental dropping of theupper locking-lever, although the hinges of both said lovers are unitedso tightly as to prevent any ordinary jarring from affecting theirposition. If preferable, but one locking-lever need be used, this beinghinged at or near the center of the box and covering an opening in theside of said box extending from 5 simply placed against the jamb in theposition specified and the thumb-screws inserted in the holes in the boxand screwed into the jamb by hand. hen the fastener is removed, thethumb-screws are placed in the box and the levers folded in to close theopen side. The box form for the body of the fastener is used in order toform a receptacle for the said screws and keep all the parts of thefastener together in a convenient form. The use of the doublelocking-levers is of great advantage, as they offer a more extended andeifectual resistance to the opening of the door than could bepractically done by any single bolt or lever in a fastener of thischaracter.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a door-fastener, the combination, with a box having an open side,of a locking-lever hinged to said open side and adapted to close thesame and a removable device for securin g the fastener in place,substantially as and for the purpose specified.

2. In a door-fastener, the combination, with a box having an open side,ofa locking-lever hinged at each end of said open side of the box, thelocking-levers being adapted to fold toward each other and close saidopen side and having their meeting ends beveled and constructed to lapeach other, substantially as and for the purpose specified.

in a door-fastener, the combination with a box having an open side, of alocking-lever hinged at each end of said open side of the box, thelocking-levers being adapted to fold toward each other and close saidopen side, and a device for retaining the upper lockinglever in ahorizontal position when opened out, substantially as and for thepurpose specified.

4. In a door-fastener, the combination, with a box having an open side,of alocking-lever hinged at each end of said open side of the box, thelocking-levers being adapted to fold toward each other and close saidopen side, and a strut pivoted in the box and having its free endadapted to engage a shoulder in the upper locking-lever when opened outin a horizontal position, substantially as and for the purposespecified.

5. In a door-fastener, the combination, with a box having an open sideand openings through opposite sides, of 1ocking-levers hinged at theends of said open side, adapted to fold together and close the same, themeeting ends of the locking-levers being beveled and constructed to lapeach other, a pivoted strut constructed to hold the upper lockingleverin a horizontal position when opened out, and screws adapted to engagesaid openingsthrough the opposite sides of the box and hold the fastenerin place, substantially as and for the purpose specified.
